ABSTRACT Ongoing climate change is negatively impacting crop productivity globally. Past research has highlighted that a diverse soil microbial community and variation in plant traits for resource acquisition can mitigate the negative impacts of factors on productivity. This study investigates effects two major environmental stressors—drought salinity stress, productivity, biomass allocation, root leaf trait responses under distinct diversities. Our results showed stress had stronger than drought stress. Shoot decreased by 30% 32.5% respectively, whereas 32% only Soil diversity did not affect Next, were mainly impacted both stresses diversity. Specific length specific area drought, tissue density was minimal Root affected communities. In contrast, nitrogen content increased, pheophytin (a breakdown product chlorophyll) when plants grown communities stresses, especially drought. These highlight importance response to stresses.

The extensive use of chemical fertilizers has served as a response to the increasing need for crop production in recent decades. While it addresses demand food, resulted decline productivity and heightened negative environmental impact. In contrast, plant probiotic bacteria (PPB) offer promising alternative mitigate consequences fertilizers. PPB can enhance nutrient availability, promote growth, improve uptake efficiency, thereby reducing reliance on fertilizers.This study aimed evaluate impact native Rhizobium strains, specifically calliandrae LBP2-1, mayense NSJP1-1, jaguaris SJP1- 2, quality, rhizobacterial community tomato crops. Various mechanisms promoting growth were investigated, including phosphate solubilization, siderophore production, indole acetic acid synthesis, cellulose cellulase production. Additionally, involved assessment biofilm formation root colonization by GFP-tagged conducted microcosm experiment, analyzed microbial using metagenomics rhizospheric soil.The results showed that rhizobial strains NSJP1-1 SJP1-2 had ability solubilize dicalcium phosphate, produce siderophores, synthesize acid, colonization.

Intensive agriculture uses continuous chemical fertilizers to increase crop yields, but excessive use of leads environmental pollution, permanent changes in physicochemical conditions soil ecology, deterioration biological health, leaching nutrients, surface and groundwater pollution eutrophication. Plant growth-promoting rhizobacteria (PGPR) are becoming increasingly important for ensuring safety, increasing nutrient uptake output, lowering fertilizer costs, preventing contamination promoting sustainable agricultural resources. Therefore, the purpose this study was identify evaluate effects fifteen bacteria strains that were isolated from various acidic rhizospheric soils as biofertilizers on properties. Growth, yield quality traits analyzed, PGPR identified using 16S ribosomal RNA Turkish oregano. Fifteen bacterial inoculations with 1-aminocyclopropane-1-carboxylate (ACC) deaminase, N2-fixing, P-solubilizing and/or IAA-producing genes used experiment, which carried out a randomized block design five replicates (each three pots) control without inoculation. Increased activity inoculated multiple confirmed by high C N content microbial biomass, urease, dehydrogenase acid alkaline phosphatase activities. Essential oil content, yield, thymol carvacrol contents increased 0.5–40.1%, 5.9–71.9%, 0.07–16.7% 0.3–9.2%, respectively, result Oil ranged 2.02% 2.83%; (66.1–72.2%) main constituent, followed (14.5–16.9%) linalool (1.38–3.68%).

Abstract Plant growth promoting rhizobacteria are a diverse group of microorganisms that enhance the plants under various conditions. In this study, 55 isolates endogenous were collected from rhizosphere Avicennia marina, Suaeda vermiculata, Salsola soda, Anabasis setifera, Salicornia europaea, Arthrocnemum macrostachyum, Limonium axillare, Tetraena qatarensis, Aeluropus lagopoides, and Prosopis juliflora . The evaluated in-vitro for their antagonist potential against Fusarium oxysporum Botrytis cinerea using dual culture technique, where maximum inhibition reached 49% 57%, respectively. In-vivo evaluation was accomplished to determine growth-promoting greenhouse conditions strain ANABR3 ( Bacillus subtilis ) showed strongest effects. Further in-vivo testing regarding effectiveness in presence phytopathogen also completed Hoagland medium. LEMR3 SALIR5 (both identified as two strains B. supported tomato seedlings overcome disease significantly p ≤ 0.05) increased above belowground biomass compared control. Additionally, several characterizing tests carried out on selected strains, these found possess numerous features promote plant directly indirectly such production IAA, HCN, hydrolytic enzymes, ACC deaminase, NH 3, some capable phosphate solubilization. conclusion, study local rhizobacterial arid lands valuable traits, making them promising bio-control agents bio-fertilizers agricultural purposes.

Abstract Soil fertility and productivity are severely impacted by exploitation degradation processes. These threats, coupled with population growth climatic changes, compel us to search for innovative agroecological solutions. Prebiotics, a type of soil biostimulant, used enhance conditions plant may play role in carbon (C) sequestration. Two commercial prebiotics, K1® NUTRIGEO L® (referred as SPK SPN, respectively), were assessed their effects on agricultural cultivated Zea mays L., compared untreated or control (SP). Analyses performed at two harvesting dates: three weeks (D1) ten (D2) after the application prebiotics. Plant parameters characteristics measured, focusing organic matter, bacterial fungal communities, root mycorrhization. Regarding physicochemical parameters, both prebiotic treatments increased electrical conductivity, cation exchange capacity, soluble phosphorus (P) while decreasing nitrates. Meanwhile, SPN treatment was distinct elevating specific cationic minerals, such calcium (Ca) boron (B), D2. At microbial level, each induced unique shift indigenous communities’ abundance diversity, evident Simultaneously, taxa recruited treatment, Caulobacter , Sphingobium Massilia from bacteria Mortierella globalpina Schizothecium carpinicola fungi well Chitinophaga Neobacillus Rhizomicrobium Sordariomycetes minutissima SPN. biomarkers identified (a) saprotrophs, (b) growth-promoting fungi, (c) endohyphal bacteria, (d) endophytic symbiotic microbiota.
